OIL-BURNER.

Specification of Letters Patent. Patented NOV, 14, 1911,

Application led January 26, 1910. Serial No. 540,140.

To all whom it may concern:

Be it known that we, WILLIAM MGK. BURNS, a resident of Concordia, in thecounty of Cloud and State of Kansas, and ROBERT IV. BURNS, a resident ofCherryvale, in the county of Montgomery and State of Kansas, bothcitizens of the United States, have invented a new and ImprovedOil-Burner, of which the following is a full, clear, and exactdescription.

rThe invention relates to oil burners, and has for an object to providea burner adapted to use oil as fuel for heating.

A further object of our invention is 'to provide a burner having acombustion chamber adapted to receive oil therein, the said oil beingignited and diffused in a manner adapted to generate heat suitable forvarious purposes, as will be hereinafter more fully specified.

Our invention embodies a feed pipe inserted through an air chamber andterminating in a mixing chamber where oil owing from the feed pipe isadapted to mix with air from the air chamber, and thesaid mixture isthen passed into a combustion chamber where, by suitable ignition means,the resulting combustion produces heat which rises upwardly into afirebox and is then distributed to act on the various elements which areto be heated.

Our invention is particularly adapted for cooking or for heating roomsand the like, and can be readily secured in stoves originally designedfor the use of coal as a fuel.

Our invention still further -embodies certain novel features ofconstruction as will be hereinafter more fully described and specifiedin the claims. l I

Reference is to be had to the accompany-V ing drawings forming a part ofthis speciiication, in which similar characters of reference denotecorresponding parts inall the views, and in which- Figure 1 is aperspective view of a stove equipped with our invention, parts of thestove and oil burner being broken away to show the underlying structure;Fig. 2 is a fragmentary sectional side view of the stove, showing thelocation and various chambers of the oil burner; Fig. 3 is a sectionalplan view taken on the line 3 3 in Fig. 2, and Fig. 4 is a sectionalview taken on the line 1 -4 inFig. 2, and showing the In the lire pot ofa stove A, of any preferred make, is disposed over a grate B, a conduitC. At the point D in the conduit C is an air inlet extending from theexterior of the stove A through a door E to the ink side of the stove.The air inlet is preferably circular in shape and in the conduitadjacent the air inlet and at the point F a mixing space is formed.Adjacent the point F, or mixing space, a combustion space is provided atG and disposed over the combustion space is a rebox H extendingtransversely to the inner terminal of the conduit C and provided withangular sides I as will be seen in Fig. 2.

A partition J having apertures J and suitable cross bars J 2 on bothsides of a centrally disposed member J 3, is disposed over the frebox Hand forms a base for a heating chamber or oven K extendinglongitudinally to the firebox, overthe same. The heating chamber Kcomprises angular sides L extending upwardly to within a distance of theunderside M of the stove top N, with the exception of one side O, whichextends upwardly only a short distance so as not to interfere withl thedraft flue P of the stove A. The partition J has portions Q extendedfrom both ends of the partition J for the purpose of strengthening andmore securely holding the partition J in place.

Depending from a bracket R, on the conduit C, is a feed pipe S, havingan end T turned downwardly as will be clearly seen by referring to Fig.2. The feed pipe S extends outwardly through the air inlet D andconnects with a tank placed a distance from the stove A and adapted tocontain fuel such as oil. It will be seen that the stove A is lined withsuitable fireclay P and that the angular sides L of the heating chamberor oven K are slanted at a convenient angle so as not to interfere withthe lids V of the stove A. When it is desired to operate the burner, oilis permitted to drop into the conduit C at F, from the supply pipe STHere the oil fumes and air from the air inlet D combines to produce arich inflammable mixture. Suitable igniting means, comprising forinstance, a burning piece of oil soaked cotton held on one end of a longstick, is then extended through the air inlet D into the conduit C tothe point F, where, coming into contact with the mixture of oil and air,the,

said mixture combusts in the space Gr of the conduit, from which theflames produced rise into the rebox H and the heat generated is diusedby the partition J through the heating chamber K, thereby heating thecontents of any vessels that may be placed on top of the stove A or setover the openings of the same in the top plate of the stove. By means ofa suitable regulating cock or the like, the amount of oil fed into theconduit C from the oil supply pipe S, can be easily regulated and aneven degree of heat can be maintained in the heating chamber K.

It will be expressly noted that our invention can be very readily placedin any well known'stove, regardless of the nature of the fuel previouslyused in the stove and it will be understood that any suitable ignitingmeans can be employed to initially ignite the oil in the conduit. Itwill be still further understood that we do not limit ourselves to theprecise construction as shown in the drawings, the scope of ourinvention being fully defined in the appended claims.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:

l. The combination with a stove, of an oil burner therefor adapted to beinserted in the lire box of the stove and supported upon the gratethereof, said burner comprising a conduit resting upon the grate andleading out through one side of the stove,the inner end of the conduitextending upwardly, a feed pipe extending into the conduit and having adownwardly discharging inner end arranged adjacent to the upwardlyextending inner end of the conduit, a burner fire box supported upon theconduit and into which the inner end of the conduit opens, said burnerfire box having a top provided with openings on each side of the centerthereof, and a heating chamber above the burner fire box and having itsrear wall terminating short of the bottom of the flue of the stove, theother walls of the chamber extending to within a l short distance of thetop of the stove.

2. An oil burner for stoves, comprising a conduit adapted to rest uponthe grate of a stove with its outer end extending out through a side ofthe stove, a feed pipe extending into the conduit and having adownwardly discharging end arranged adjacent to the inner end of theconduit, a fire box supported upon the inner end of the conduit and intowhich the said conduit opens, said fire box having a top provided withopenings on each side of the center thereof, and a heating chamber, thebottom of which is formed by the top of the fire box, the heatingchamber having one of its walls of less height than the others.

3. An oil burner for stoves, comprising a conduit having an upwardlyextending inner end and adapted to rest on the grate of a stove, a feedpipe extending into the conduit and having its inner end arrangedadjacent to the upwardly extending inner end of the conduit, and a firebox supported upon the said inner end of the conduit, and into which thesaid conduit opens, said fire box having a top provided with openings oneach side of the center thereof.

4. An oil burner for stoves, comprising a boxlike structure open at thetop and having an apertured partition dividing it into a fire box and aheating chamber, a. conduit upon which the structure is supported,having an upwardly extending inner end opening into the ire box of saidstructure, and a feed pipe extending into the conduit, the whole beingadapted to be placed in a stove with the conduit resting upon the gratethereof.
